ENGLISH 11. How to Take Proper Measurements (1) Preparation before measurement Always measure in the same arm (generally the left arm). --Remain still and keep quiet during measurement. --Relax as much as possible and do not talk during measurement PROCEDURE. --Measure your blood pressure at about the same time every day. --Do not measure right after physical exercise or a bath. Rest for 20 to 30 minutes before taking the measurement. --Readings under the conditions listed below may affect results: Within an hour after dinner, after having wine, coffee, tea, sports; talking, being nervous, being in unsteady mood, bending forward, moving, room temperature dramatically changing during measuring; inside a moving vehicle, repeated and continuous measuring. (2) Wearing the cuff correctly 1) Unroll the cuff. Place your arm inside it. (We strongly recommend to use your left arm.) 2) Make sure that the device’s screen is positioned on your inner arm as illustrated in the diagram. The bottom edge of the cuff should be 0.8-1.2 inches (2 to 3 cm) above the inside elbow.
Page 10
ENGLISH 3) Tighten the cuff around your arm, so it can not move around your arm. Note: Repeated measurement may result in blood congestion in the arm, which will affect the measurement result. Be careful not to rest your arm on the air tube.To avoid this situation, we advise that you can raise the left hand and hold the fist for several times, or take off the cuff and rest for at least 2-3 minutes before taking the measurement. (3) Measurement tips • To take a measurement, you need to be relaxed and comfortably seated in a room with a comfortable temperature. • Sit in a comfortable chair with your back and arm supported. • Keep your feet flat and your legs uncrossed. • The device should be placed on your inner arm at the same level as your heart, with the arm resting comfortably on a table. (4) Taking a measurement Press the “ “ button and the monitor will begin to inflate. Please do not move or talk during the measurement.
Page 11
ENGLISH Note: If you feel uncomfortable during the measurement, press the “ “ button immediately to stop measure. When the air pressure is filled to a certain value, the value on the display screen will slowly drop at a certain speed, and the heartbeat symbol will flash. After the measurement is completed, the systolic pressure, diastolic pressure, and pulse measurements will be displayed on the screen. Note: Consult your doctor if unexpected readings are obtained. (5) Memory function 1) Each measured value is stored automatically under the appropriate “User” group. This device can store up to 120 sets of measurements for each user. (Note: There is no memory for “Guest”.) Once the memory log is full, old values are refreshed with new ones.
ENGLISH (8) “Keep Still” indication The “ “ icon flashes when you move the body or shake the hand during the measurement, which may cause incorrect measurement results. Please measure again. (9)Turn off the unit Press “ “ button to turn off the arm blood pressure monitor. The monitor automatically turns off after 1 minutes. 12. Warnings and Cautions Warnings ● No maintenance or servicing when using. ●Too frequent measurements can cause injury to the PATIENT due to blood flow interference. ●Consult with your physician before using this monitor on an arm where intravascular access or therapy, or an arterio-venous (A-V) shunt, is present because of temporary interference to blood flow which could result in injury. ●Consult with your physician before using this monitor if you have had a mastectomy or lymph node clearance. ●Do not use the monitoring ME EQUIPMENT on the same limb simultaneously. This could temporarily cause loss of function or an inaccurate measurement. ●Please check whether the operation of the Arm blood pressure monitor leads to prolonged impairment of patient’s blood circulation by observing the limb concerned.

ENGLISH ● DO NOT use this monitor for infants, toddlers, children or persons who cannot express themselves. ● DO NOT take medicine based on readings from the device. Contact your physician for specific information about your blood pressure. The patient should not self-diagnose or self-medicate per measured results. Kindly adhere to the instructions of your physician or health provider. DO NOT use the device while you are on an intravenous drip or blood transfusion. ● DO NOT use this monitor in areas containing high frequency (HF) surgical equipment, magnetic resonance imaging (MRI) equipment, computerized tomography (CT) scanners. This may result in incorrect operation of the monitor and/or cause an inaccurate reading. ●Make sure that the cuff is not placed on an arm in which the arteries or veins are undergoing medical treatment, e.g. intravascular access or intravascular therapy,or an arteriovenous(AV)shunt. ● Consult with your physician before using this monitor if you have common arrhythmias such as atrial or ventricular premature beats or atrial fibrillation, arterial sclerosis, poor perfusion, diabetes, pregnancy, pre-eclampsia or renal disease. NOTE that any of these conditions in addition to patient motion, trembling, or shivering may affect the measurement reading. ● Stop using this monitor and consult with your physician if you experience skin irritation or discomfort. ● Consult with your physician before using this monitor if you have severe blood flow problems or blood disorders, because the cuff inflation can cause bruising. ● DO NOT use this monitor for any purpose other than measuring blood pressure and pulse rate. ● DO NOT disassemble or attempt to repair this monitor or other components. This may cause an inaccurate reading. ● DO NOT use in a location where there is moisture or a risk of water splashing this monitor.
ENGLISH several minute. ●Do not operate when charging. 13. Common Q & A on Blood Pressure Q1: Why is the blood pressure value obtained at home lower than that obtained at the hospital? ● The blood pressure difference between home and hospital measurements is about 20 mmHg - 30 mmHg (2.7 kPa - 4.0 kPa). This is because individuals tend to be more relaxed at home than at the hospital. ● Also, when the device is placed at a position over the heart, the blood pressure value tends to be much lower than it actually is. Ensure the device is positioned right at the heart level. Q2: Why is the blood pressure value obtained at home higher than that obtained at the hospital? ● The anti-hypertensive drug the patient might be using has lost its efficacy. Kindly adhere to your doctor’s instructions.
ENGLISH 5mmHg-10mmHg (0.7kPa-1.3kPa) lower than the first time. This will be more obvious for those with higher blood pressure. --When continuous measurement, please note that: There might be extravasated blood because the arm is compressed, resulting that the finger tip blood does not flow smoothly, If you continue the measurement in case of extravasated blood, you cannot obtain the correct measured value. Loosen the arm band, raise your hand over the head, and grasp and stretch your left and right palms for 15 times repeatedly. Then the extravasated blood can be dissolved, and you can continue the blood pressure measurement. 2) Cuff position and twining method. The measured value varies with the cuff size. Particularly, if the cuff is twined round the elbow, you cannot obtain the correct measured value. --Please use the correct cuff twining method for measurement. The arm circumference range of the enclosed cuff is 22~42cm (center of the upper arm). If the model is inconsistent, please purchase separately. 14. Abnormal Phenomena and Handling If the measurement is abnormal, any of the following symbols may appear. Kindly use the recommended method for measurement. Errors Cause The inflation can not reach 30 mmHg Er U in 12 seconds. Er H The inflation reaches 295mmHg, Er 1 The pulse rate is not detected correctly. Too much disturbance (Move, talk, or magnetic Er 2 disturbance during a measurement).

16. Upkeep and Maintenance - Always keep the surface of monitor clean and tidy, helpful to prolong the service life of Blood Pressure Monitor. - If the host is dirty, please wipe with a dry soft cloth. If the dirt cannot be eliminated easily, wipe with a soft cloth stained with water or neutral detergent, and then dry with a dry cloth. -We suggest to calibrate the monitor once a year at least. Please contact manufacturer or agent if you need. Warning: Do not allow water or other liquids to flow into the device.The arm pressure monitor should not no longer be reused when liquid enter and damage the device and cuff. 17.
